Just as you will continue to post freak hurricanes.Quote:

that sounds like a very reasonable post, with which i agree, until you reach the very end.Quote:

Biologist says global warming could reduce Arkansas duck numbers
By DANIEL CONNOLLY
The Associated Press
LITTLE ROCK — A professor from the University of Montana had a simple message Tuesday in Arkansas: if you like hunting ducks, support international efforts to prevent global warming.
Wildlife biologist David E. Naugle said that, if global temperatures rise, duck breeding grounds in North America will dry up, greatly reducing duck populations.
He said the best way to solve the problem is to work with other countries to reduce emission of carbon dioxide.
“This is a global problem that’s going to require global solutions,” he said.
Naugle’s trip to Arkansas was paid for by the Natural State Coalition, a new group that’s dedicated to combating global warming.
Most scientists say carbon dioxide produced by burning fossil fuel such as coal and oil traps heat in the atmosphere, which leads to increased surface temperatures.
In Arkansas, duck hunting is both a beloved pastime and a source of income for businesses that depend on hunters’ dollars. In the eastern Arkansas town of Stuttgart, for instance, the annual Wings over the Prairie Festival draws thousands of people for a festival that includes a highly competitive series of duck calling contests.
Speaking near a park pavilion on the banks of the Arkansas River, Naugle described research he and associates published last fall in the scientific journal BioScience.
The research focused on the prairie pothole region, which includes parts of Iowa, Minnesota, Nebraska, North Dakota and South Dakota as well as the Canadian provinces of Alberta, Manitoba and Saskatchewan.
The region, which includes large swaths of wetland, is the breeding ground for 50 to 80 percent of the ducks that migrate to Arkansas each year, he said.
A 95-year climate history of the region shows that it has become warmer on average, he said.
Researchers produced computer models that tested what would happen if average temperatures rose 3 degrees Celsius. The result: the available breeding ground for ducks would shrink dramatically. The breeding ground would shrink even further if precipitation decreased 20 percent at the same time, he said.
That would mean hunters in Arkansas would see smaller duck populations.
Last month, an aerial survey in Arkansas counted 289,589 ducks, about half as many as last year. State officials blamed the low numbers on a drought.
Naugle said the current low duck population isn’t necessarily related to global warming: it may be due to the local drought, changes in bird migration patterns, and changes in the way rice farming is conducted.
However, global warming remains important. “If we can’t produce the ducks on the breeding grounds, it’s a moot point where they go after this,” he said.
The Natural State Coalition is led by Robert McLarty and has existed for only two months. McLarty, 30, has worked as a political consultant and said he wants to create a coalition of duck hunters, bird watchers, environmental organizations and other groups to educate the public on global warming.
haven't you posted that before? what would happen to duck hunting in arkansas if "global warming" caused a new ice age?Quote:

New source of global warming gas found: plants
Wed Jan 11, 1:06 PM ET
LONDON (Reuters) - German scientists have discovered a new source of methane, a greenhouse gas that is second only to carbon dioxide in its impact on climate change.
The culprits are plants.
They produce about 10 to 30 percent of the annual methane found in the atmosphere, according to researchers at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany.
The scientists measured the amount of methane released by plants in controlled experiments. They found it increases with rising temperatures and exposure to sunlight.
"Significant methane emissions from both intact plants and detached leaves were observed ... in the laboratory and in the field," Dr Frank Keppler and his team said in a report in the journal Nature.
Methane, which is produced by city rubbish dumps, coal mining, flatulent animals, rice cultivation and peat bogs, is one of the most potent greenhouse gases in terms of its ability to trap heat.
Concentrations of the gas in the atmosphere have almost tripled in the last 150 years. About 600 million tonnes worldwide are produced annually.
The scientists said their finding is important for understanding the link between global warming and a rise in greenhouse gases.
It could also have implications for the Kyoto Protocol, which calls for developed countries to cut their emissions of greenhouse gases by 5.2 percent below 1990 levels by 2008-12.
Keppler and his colleagues discovered that living plants emit 10 to 100 times more methane than dead plants.
Scientists had previously thought that plants could only emit methane in the absence of oxygen.
David Lowe, of the National Institute of Water and Atmospheric Research in New Zealand, said the findings are startling and controversial.
"Keppler and colleagues' finding helps to account for observations from space of incredibly large plumes of methane above tropical forests," he said in a commentary on the research.
But the study also poses questions, such as how such a potentially large source of methane could have been overlooked and how plants produced it.
"There will be a lively scramble among researchers for the answers to these and other questions," Lowe added.
